I have a 98 so im not sure what injectors I need since half way they changed. Was told just to check the plug if its round or square or something or if its black or orange. Heres a pic of mine.

 

If your looking for factory injectors then these are the ones you are looking for:

'96-'99, ........53030778, ...Grey, .........49psi, .................23.2lb/hr

Part number is 53030778. Although Ford injectors would probably work better since the spray pattern is much better. Im not positive which ford injectors you need though. Im using yellowtops on my Renix but you will need a different one for yours since you have an H.O.
